While working on this exercise, I was getting problems wrong because I wasn't focusing on my algebra. A box saying I should try watching a video appeared, I hit the "x" to close this box. The next problem came up with code on the page and I cannot progress any further. The code appears as follows:

SOLUTION
var eq1 = A + "x + " + B + "^\\circ"; var eq2 = C + "x + " + D + "^\\circ"; init({ range: [ [ -1, 5 ], [-1, 1] ] }); graph.pl = new ParallelLines( 0, 0, 4, 0, 0 ); graph.pl.draw(); graph.pl.drawTransverse( ANCHOR ); graph.pl.drawAngle( KNOWN_INDEX, eq1 ); graph.pl.drawAngle( UNKNOWN_INDEX, eq2, "#FFA500" );
